Abstract
PARA EL ESTABLECIMIENTO DE CONFERENCIAS TRIANGULARES, HAY PREVISTA UNA UNIDAD DE CONFERENCIAS (KE) CON UNA PROM, EN LA QUE ESTAN GRABADAS TODAS LAS POSIBLES SUMAS Y DIFERENCIAS DE COMPRESIONEXPANSION CORRESPONDIENTES A LAS APORTACIONES DE DOS ABONADOS, Y QUE SON CONTROLADAS POR LAS APORTACIONES INDIVIDUALES COMO DIRECCIONES DE CONTROL DE LECTURA. LA PROM REALIZA AQUI LAS FUNCIONES DE LINEALIZACION DE LAS SUMAS Y DIFERENCIAS Y DE LA COMPRESIONEXPANSION, QUE HASTA AHORA ERAN CONTROLADAS POR UNIDADES SEPARADAS.
